VINCENT I-I. SOISSON, OF CONNELLSVILLE, PENNSYLVANIA.

Application 1ed40ctober 11, 1917.

To all whom t may concern.'

Be it known that I, VINCENT H. SoIssoN, a citizen of the United Sltates,residing at Connellsville, in the county yof Fayette and State ofPennsylvania, have invented a new and useful Machine for Making SilicaBrick, of whichlthe following is a specification. i

This invention relates to machines for making silica brick.

Bricks of this character have heretofore been produced by Vfirsthammering the material into a mold so as to pack all corners oi the moldin order to produce a brick of the proper finish. This has been alaborious and expensive undertaking and `it is an object of the presentinvention to provide mechanism which will handle the materialautomatically, thus increasing` the output and lessening the cost ofproduction.

Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention has"been shown.

In said drawings Figure 1 is a central longitudinal section through themachine.

Fig. 2 is a side elevation thereof.

Fig. 3 is an elevation of the mold mechanism.

Fig. 4 is a section on line A-B Fig. 3.

Fig. 5 is an elevation of a modified form of mold tapping mechanism.

Fig 6 is a section on line C-D Fig. 5.

Referring to the figures by characters of reference 1 designates astructure support ing a hopper 2 the inclined bottom 3 of which leadsdownwardly to a ledge 4 extending into the hopper and constitutingacontinuation of a guide 5. An opening 6 is provided in the bottom ofthe hopperl and above the ledge 4 and mounted for movement in thisopening is a plunger 7 connected to an actuating rod 8. This rod carriesan anti-friction roller 9 and a weighted cord 10 or the like connectedto the rod 8 serves to hold the plunger 7 normally retappingSpecification of Letters Patent.

tracted into the opening 6. This weighted cord is mounted on a. pivotalguide sheave 11 as shown.

The hopper is divided by a vertical partition l2 into two compartments13 and 14 respectively. The inclined bottom 3 is arranged under thecompartment 13 and the partition l2 terminates above the inner end ofthe ledge 4 and practically in horizontal alinement with the upper wallof the opening 6. A plate 15 forms the bottom of the compartment 14 andhas an outlet opening 16 therein the walls of which converge downwardly.A tamping rod 17 is mounted for reciprocation within the compartment 14and has a foot 18 at its lower end while its upper end is slidablymounted within a bracket 19 connected to a beam 20 pivotally mounted asat 21 above the hopper 2. A spring 22 is mounted on the rod andconstitutes a cushioning means for transmitting motion from the beam 20to the rod 17 during the downward movement of the beam. This spring isinterposed between bracket 19 and a collar 22 secured to or formed `onthe rod 17.

A table 23 is arranged under the hopper and is spaced from the plate l5a distance substantially equal to the height of a mold 24. This tablehas an opening 25 therein directly under the opening 16 and mountedwithin the opening 25 is a slide 26 having ber 29 having spaced openings30 in each of which is mounted a slidable block 31. Each block isconnected by a pitman 32 to a crank 33 carried by a shaft 34. This shafthas a series of cranks which are out of alinement with each other andeach crank is connected to one of the blocks 3l. Vithin each block isslidably mounted a head 35 having a stem 36 the lower end of which hasany suitable means, such as a nut 37, for limiting the upward movementof the head relative to the block. A spring 38 is mounted on the stemand within each yieldable support for the head 35.

A propelling rod 39 extends above the loosely clutch table 23 and hasthat end thereof above the table preferably mounted on anti-frictionrollers 40 or the like, while the other end of the rod is preferablyprovided with an anti-friction roller 41. A weighted cord 42 is attachedto the rod 39 and is mounted on a guide sheave 43 or the like, this cordserving to hold the rod 39 normally retracted away from the mold on thetable 23.

A longitudinal shaft 44 is journaled within the structure 1 and isprovided, at one end, with a crank arm 45 the Wrist pin 46 of which isjournaled in a block 47 mounted in a slot 48 extending longitudinallywithin a pitman 49. One end of this pitman is pivotally connected to thebeam 20. Notches 50 are provided in the sides of the slot 48 and any ofthese notches are `designed to receive a receiving plate 51 which,

when in position, serves to limit the movement of the block 47 withinthe slot 48. When the parts are arranged as in Fig. 2,

block 47 is held against sliding movement in the slot. Obviously,however, by shifting the plate 51 into some of the other notches in thewalls of the slot, block 47 is capable of a limited sliding movement,thus reducing the movement of beam 20 duringthe rotation of the crankarm 45.

A large driven gear 52 is secured to one end portion of the shaft 44 andcarries, upon one face, two cams 53 and 54 respectively. Cam 53 isdesigned to move against the roller 9, while cam 54 is adapted to moveagainst the roller 41. Gear 52 meshes with and receives motion from asmaller gear 55 which is secured to a drive shaft 56 which may beoperated in any suitable manner, as by means of a belt, not Ashown,mounted on a pulley 57. A gear 58` is member 59. Another clutch member60 is feathered on the shaft 56 and the two clutch members 59 and 60 areyieldingly pressed apart by a spring 61. An arm 62 extends from theclutch member 60 and into the path 'of a cam 63 on the gear52. Gear 58constantly meshes with a gear 64 secured to a shaft 65. This shafttransmits motion through gears 66 and 67 to the shaft 34 hereinbeforereferred to. y, In using the apparatus the compartment 13 of the hopperis partlyor entirely filled with the material of which the bricks are tobeformed. A mold 24 is placed between the-plate 15 and slide 26 and anadditional mold is placed between said mold 24 and the rod 39.

The parts are so timed that immediately following the placing of a mold24 under the opening 16 by the shifting of rod 39 by cam 54, the tampingrod 17 will be elevated and as this tamping rod begins its upwardmovement, plunger 7 will be` projected inwardly, thus forcing under thetamping mounted on shaft 56 and hasV ai rod 17 that portion of thematerial lying in the path of the plunger 7. Immediately following orsimultaneously with this action the cam 63 comes against arm 62 andthrusts the clutch member 60 into engagement with clutch member 59 sothat gear 58 will thus be coupled with the rotating shaft 56.Consequently `motion will be transmitted to the crank shaft 34 andslides 31 will be rapidlyV reciprocated, causing the Ayieldinglysupported heads 35 to` tap Vthe bottom of the slide 26, which tappingwill be transmitted through the slide to the mold thereabove.Consequently the material discharged under the tamping rod by theplunger 7 will gravitate into the mold and the tapping of the mold willcause portions of the material to pack in all of the corners of themold. The plunger 7 then retracts into the opening 6 and tamping rod 17descends, pressing the material tightly into the mold. The tapping dueto the rotation of the shaft 34 ceases as the tamping rod becomesedective and as soon as the material has been properly packed within theopening 16 and the mold 24 thereunder and said rod 17 begins its ascent,rod 39 will be thrust longitudinally by its cam 54, pushing a new moldinto position under the plate 15 while the filled mold will be forcedout of position. During the removal of the filled mold, the lower edgesof the walls 'of the opening 6 will act as cutters and will scrape offthe material from the top of the mold, leaving -the molded brickssmooth.

From the foregoing it will be apparent -that it becomes unnecessary topack any of the material by hand and all of the large particles aswellas the smaller particles will be received in the mold andproperly packedwithout hammering the material by hand as heretofore.

Obviously instead of tapping the mold in the manner pointed out, thestructure illustrated in Figs. 5 and 6 may be utilized. By referring tothese figures itwill be noted that aslide 68 is arranged under the mold69 and this slide, which may, be Vprovided with rollers 70, has springs71 under it. Each spring is adapted to be engaged by spaced projections72 formed on a wheel 73, all of the wheels being attached to a'shaft 74corresponding with the shaft 34 heretofore referred to. Thus it will beseen that `when said shaft 74 is rotated theY projec- 71 and will causethe slide 68 to be rapidly vibrated, thevibrations being transmitted tothe mold 69 with the result that the material dischargedinto the moldwill be properly packed. l

, As shown in Fig. 1 the arm 62 can be eX- tended downwardly so that itslower end Will slide Within a guide slot 75 so as thus to be heldagainst rotation with the shaft 56.

Guide brackets 76 can be mounted on the frame of the machine forsupporting the rods 8 and 39.

lVhat is claimed is:

l. The combination with a mold support, means for feeding a charge ofmaterial into position above a supported mold, of means` for jolting themold support during the feeding of the mold, and means for tamping themold.

2. The combination with a mold support, and an apertured feed platethereabove, of means for automatically feeding a charge of material ontosaid plate, means for automatically jolting the mold support to packmaterial by gravity Within the mold, and means for automatically tampingmaterial through the feed plate and into the mold.

3. The combination with a mold support, of mechanism thereunder forintermittently tapping said support, means for successively directing amold onto the supportI and 0E of said support, a feed plate above thepath of the mold and having an aperture therein, means for directingcharges of material onto the feed plate when a mold is in positionthereunder, means for automatically operating the tapping mechanismduring and subsequent to the feeding of the charge of material to themold, and means for automatically tamping the material through the feedplate and into the mold.

4, rlhe combination with a mold support and tapping mechanism thereunderand cooperating therewith, of a drive shaft, a Wheel driven thereby, abulk holder, separate means operated in timed relation by the Wheel forsuccessively directing a charge of material from the bulk holder andinto a mold, tamping the material in the mold, and ejeeting the mold,and means controlled by said Wheel for automatically coupling thetapping mechanism to and uncoupliing` it from the drive shaft to tap thesupported mold While a charge is being fed into the mold.
